Cornerpiece for flexible siding

J. F. HQNAN CORNERPIECE FOR FLEXIBLE SIDING Filed March 25, 1955 J 7. Ham/v ATTORNEY Patented Oct. 6, 1936 rso s'r'rss FATE! QFFIQE My invention relates to building construction, and particularly to the finishing of exterior walls of wooden buildings and the like by the application thereto of weather-boarding or sidings of flexible composition strips in successively overlapping relation.

Within a comparatively recent period there has been commenced in building construction an extensive use of flexible composite material for the exterior finish of walls. A typical material of the class mentioned comprises strips of asphaltimpregnated felt having an adherent surfacecoating of granular material in contrasting colors, applied in a suitable pattern such that when the strips are overlapped in the assembly thereof upon a wall, the surface-areas of one color simulate bricks, while a mortar-joint between the bricks is simulated by areas of different color exposed at the lower edges, and through notches in the lower edges, of the strips. In the application of the material it is diificult to cut it evenly at the corners and much time is consumed in the operation and even with the use of considerable care and skill the corner joints have a ragged appearance. The edges at such corner joints have a tendency to curl outwardly from the side of the building thereby permitting air and moisture to work under the siding.

It is therefore the object of my invention to provide, for use with sidings of the character mentioned, durable, inexpensive and efil'cient means for covering and finishing the corners of buildings, and producing a permanent, sightly and efficient joint between the adjoining ends of the siding-strips at the corners of any structure to which the same are applied.

A further object of my invention is to provide a metallic corner-piece for use with overlapping sidings, especially adapted for locking together the adjacent ends of siding-strips of flexible composite material, and wherewith the nails or fastening means for both the sidings and the corner-pieces are covered and concealed from view in the finished structure.

Other objects of my invention will appear in the following detailed description taken in connection with the accompanying drawing where- Figure 1 is a perspective view of a corner structure consisting of flexible siding-strips and metallic corner-pieces embodying my invention, a portion being broken away to show normally concealed parts.

Figure 2 is a rear view of one of the corner pieces.

Figure 3 is a plan view of the flat blank from which a corner piece is formed.

Figure 4 is a transverse horizontal section on the line 44 of Figure 2.

Referring more particularly to the drawing reference numeral it indicates the outer boards of a structure wall at a corner thereof over which are secured by nails H strips of flexible composite asphalt-impregnated felt sidings l2 in successive courses in overlapping relation. The

adjoining edges E3 of the siding-strips at the.

corner of the structure are cut to conform to said corner and are covered by a corner-piece of metal, said corner-piece being preferably of a non-rusting material such as copper which, when weathered, will blend with the color of the siding and will be sightly without being conspicuous. The corner-piece comprises an elongated tapered body having tapered sides M, said body being angularly folded or bent along its longitudinal median, indicated by dotted line l5 in Figure 3, to fit the corner of the structure as shown in Fig. 1. At its upper or smallest end the body is provided with oppositely projecting flanges I6 integral with the respective sides, and each of said flanges is provided with a hole H for receiving a nail for securing the corner-piece to the structure above the lower edge of the succeeding overlapping piece or course of siding in order that said succeeding overlapping course or piece of siding may cover said nails to prevent the penetration of moisture or the like around said nails and through said holes and to conceal said nails from sight.

At its lower or largest end the body portion is centrally notched to provide each side It with a tongue IS. The tongues I8 are folded rearwardly along a crease line, indicated by the respective dotted lines I!) in Figure 3, to provide end portions 20.

The tongues l8 of the respective sides i l are also bent or folded upwardly along a crease line, indicated by the dotted lines 2! of Figure 3, in rearwardly spaced relation with the rear surface of the respective sides, the upper end of each tongue being spaced farther from the rear surface of its respective side than the lower end and adjacent the upper end of each tongue is swaged an inwardly extending projection 22 adapted to penetrate the under side of the asphalt-impregnated siding 12.

In applying the corner-piece the same extends transversely of the siding strips in intimate contact with the adjacent ends thereof. The end portions 20 of the corner-piece engage the lower edges of the respective siding-strips and the lower end of the corner-piece is pressed inwardly thereby bending the upper ends of the tongues l8 inwardly and forcing the projections 22 into the under side of the respective siding strips to prevent the lower portion of the sidingstrip ends from pulling from the corner-piece. The tongues l8, due to the metal thereof having little or no elasticity, will remain in the inwardly pressed position for secure and permanent gripping or clamping relation with the siding. Nails driven into the structure through holes I! firmly secure the corner-pieces and adjoining ends of the siding-strips to the structure.

Due to the corner-pieces covering and protecting the adjoining ends of the siding-strips less care and time is required in cutting said ends and the application of the siding-strips is greatly speeded up.

From the foregoing it will be readily apparent that I have provided a corner-piece that fulfills all the objects above set forth.

Having thus described my invention what I claim is:

1 A corner piece comprising an elongated body bent along its longitudinal median and having at one end oppositely extending flanges, tongues at the opposite end of the body, said tongues being rearwardly and upwardly turned in spaced relation to the body at opposite sides of the longitudinal median, and inwardly extending projections on the respective tongues.

2. A corner piece comprising a body having sides in angular relation to each other, a tongue for each side at one end of the body, each tongue being folded to extend adjacent the rear surface of its respective side and in spaced relation thereto, and an inward projection on each of said tongues.

3. A corner piece comprising an elongated body bent along its longitudinal median, oppositely extending flanges at one end of the body, rearwardly extending end portions at opposite sides of the longitudinal median, upwardly extending tongues from the respective end portions, said tongues being in spaced relation with the body, and inwardly extending projections on the respective tongues spaced upwardly a substantial distance from the rearwardly extending portions.
